In devising a name for the division that Cardinal Health Inc. will spin off this year, the company turned to what it’s bringing together. The Dublin health-care giant Monday said the name for its technology-centered clinical and medical products businesses will be CareFusion. The spinoff of the $4 billion-a-year business is expected to be completed by the end of June, when Cardinal Health’s fiscal year ends, and likely will trade its shares the New York Stock Exchange under the ticker symbol CFN.
